A client with a gastrostomy tube (GT) receives a prescription
for Osmolite® 1/2 strength enteral formula at 80 ml/hour. To
prepare a 4 hour solution, the nurse should dilute the full-
strength formula with how many ml of water? (Enter numeric
value only.) - ANSWER-160
Determine the total volume needed at 80 ml/hour x 4 hours =
320 ml. Use the formula, Desired strength/strength on Hand x
Volume = 50/100 x 320 = 160 ml of Osmolite® enteral formula,
which must be diluted to half strength. Or use ratio and
proportion, Desired strength (1/2 = 1 part : 2 parts) :: Volume of
full strength : Total Desire volume 1 : 2 :: X : 320 ml 2X = 320,
and X = 160 ml of Osmolite® enteral formula, full strength 320
ml total volume - 160 ml of fullstrength formula = 160 ml of
water to create 1/2 strength or 50% concentration.
The nurse notes that a client is receiving an oxytocin (Pitocin)
infusion via a pump that is programmed to deliver 30 ml/hour.
The available solution is Ringer's Lactated 1,000 ml with Pitocin
20 units. How many milliunits/minute is the client receiving?
(Enter numeric value only.) - ANSWER-10
,Convert units to milliunits, 20 x 1,000 = 20,000 units. Using D/H
x Q = 30 ml/hour X/20,000 units x 1,000 ml = 30 ml/hour (60
minutes) X/20 =30/60, reduce X/2 = 1/2, and 2X = 20, so X = 10
milliunits/minute OR 20/1,000 = 0.02 1000 : 0.02 :: 30 : X = 0.6 ::
1,000X X = 600 and 600/60 = 10 milliunits/minute.
A client is receiving Heparin Sodium 25,000 Units in 5%
Dextrose Injection 500 ml IV at 1,000 unit/hour per protocol for
acute coronary syndrome (ACS). The client's partial
thromboplastin time (PTT) is 76 seconds. Based on the ACS
protocol, the infusion should be decreased by 100 units/hour
for a PTT between 71 to 80 seconds. The nurse should program
the pump to deliver how many ml/hour? (Enter numeric value
only.) - ANSWER-18
Adjust the infusion to 900 units/hour (1,000 units/hour minus
100 units/hour per protocol). Using the formula, D/H x Q, 900
units/1 hour divided by 25,000 units x 500 ml = 90/5= 18
ml/hour.
The healthcare provider prescribes oxytocin (Pitocin) 0.5
milliunits/minute for a client in labor. One liter Ringer's Lactate
with 10 units of oxytocin (Pitocin) is infusing. The nurse should
program the infusion pump at how many ml/hour? (Enter
numeric value only.) - ANSWER-3
Using the formula, D/H x Q, 0.5 milliunits / 10,000 milliunits x
1000 ml = 0.05
, ml/minute. Multiply by 60 minutes = 3
ml/hour.
Docusate sodium (Colace) 0.3 grams is prescribed for a client
who has frequent
constipation. Each capsule contains 100 mg. How many
capsules should the
nurse administer? -
ANSWER-3
Using the known equivalent, 1 gram = 1000 mg, the nurse
should first convert
the dose to the same unit of measurement, which is 0.3 gram =
300 milligram.
Using the formula, Desired / Available x 1 capsule = 300/100 x
1 = 3 capsules.
A client who has a sinus infection is receiving a prescription for
amoxicillin/clavulanate potassium (Augmentin) 500 mg PO q8
hours. The available form is 250 mg amoxicillin/125mg
clavulanate tablets. How many tablets should the nurse
administer for each dose? (Enter numeric value only.) -
ANSWER-2
Using Desired/Available formula: 500 mg/250 mg x 1 tablet = 2
The healthcare provider prescribes acetaminophen elixir
(Tylenol elixir) 600 mg PO q6 hours for an adult client
experiencing pain associated with maxillofacial surgery. The
